Ira, thanks for your thoughts on REST/SOAP with PSI. My main focus is on obtaining job status from a server that already has a list of jobs and their state so I'm not really exercising PSI at it's fullest ---------------------------------------------- Harry Lewis IBM STSM Chairman - IEEE-ISTO Printer Working Group http://www.pwg.org IBM Printing Systems http://www.ibm.com/printers 303-924-5337 ---------------------------------------------- <table width=100%> <tr valign=top> <td width=40%>"McDonald, Ira" <imcdonald@sharplabs.com> 01/08/2007 03:50 PM <td width=59%> <table width=100%> <tr valign=top> <td> <div align=right>To</div> <td>Harry Lewis/Boulder/IBM@IBMUS, ps@pwg.org <tr valign=top> <td> <div align=right>cc</div> <td> <tr valign=top> <td> <div align=right>Subject</div> <td>RE: PS> REST version of PSI</table> <table> <tr valign=top> <td> <td></table> </table> Hi Harry,   A quick few thoughts.   PSI is NOT at all SOAP-specific (the WSDL could easily generate pure HTTP bindings), but PSI is RPC-style and stateful (like all IETF, PWG, and vendor print protocols), which is the exact opposite of REST.   From my reading of REST descriptions, it appears REST is verb-poor and noun-rich and stateless.  Neither PSI, nor any other real print protocol is stateless - and I can't imagine any easy transform to get there (or why you'd want to).   Since there is consistency in available descriptions of REST, designing RESTful applications seems to be a statement in the eye of the beholder.   Would you care to expand on the reason for your question?   Cheers, - Ira   Ira McDonald (Musician / Software Architect) Chair - FSG Open Printing Steering Committee Blue Roof Music / High North Inc PO Box 221  Grand Marais, MI  49839 phone: +1-906-494-2434 email: imcdonald@sharplabs.com -----Original Message----- From: owner-ps@pwg.org [mailto:owner-ps@pwg.org]On Behalf Of Harry Lewis Sent: Monday, January 08, 2007 1:15 PM To: ps@pwg.org Subject: PS> REST version of PSI Is PSI so SOAP specific that a REST version would be out of the question?
